HOSE COUPLING.

Application led' October 10, 1925. Serial No. 61,728.

-This invention relates to pipe fittings and has particular reference to a sectional coupling for pipe and hoze sections.

An important object of the invention is to provide a pipe coupling which may be very quickly connected or disconnected and which will provide a tight joint.

A further ,object of the invention is to provide a coupling particularly intended for the connection of garden hose and the like.

A still further object of the invention is the provision of a pipe coupling which is of comparatively simple design yet durable and eicient in use.

Other objects and advantages of this in vention will become apparent as the description progresses.

In the accompanying drawing forming ai part of this specification and in which like numerals are employed to designate corresponding parts throughout the same:

Figure 1 is a side elevation of a coupling constructed in 'accordancev with my invention in a partially connected position,

Figure 2 is, a central vertical sectional view through the coupling,

Figure 3 is a transverse sectional view 'taken on the line 3-3 of Figure 2,

Figure 4 is -a central vertical sectional view through vthe female coupling section,

Figure 5 is a transverse sectional view,

i taken on the line 5-5 of Figure 4, and

Figure 6 is a perspective View of the male coupling section. V l

In the drawing, wherein for the purpose of illustration is shown the preferred e'mbodiment of my invention, the numeral .10 generaliy indicates the spout of a conventional type of faucet threaded for the connection of a suitable coupling member.`

Referring now moreparticularly vto 4the structure embodying my invention, the numeral 11 designates aefemale coupling section adaptedto co-act. with a male coupling section 12 to provide .a detachable coupling. The female section 11 embodies a cylindrlcal body portion 13,and' an arcuate downward extensionwhich is out away to form a substantially'semi-circular extension 14 hav' ing an arcuate recess at the rear to facilitate the connection of the sections. Formed inte. gral with the lower edges of the extension 14 are a pair of `inwardly directed parallel ribs 15 slightly tapered at their forward extremities for engagement with the male section. The upper portion of the female The male section embodies a tubular pipe section of any desirable length and having an annular flange 19 lprovided with longitudinal'tapered lugs 20 formed' on opposlte sides of the pipe section. The sides' of these rounded vso as to permit the same to readily ride in engagement with the ribs 15 formed on the co-acting section. An intermediate annular groove 21 is formed in the upper end of the male section providing a cylindrical extension 22 engageable in thevcollar 1,7 formed on the female section 11. The lower extremity of the pipe section 12 is preferably externally screw threaded and provided a distance above its extremity with a flange of the usual type. This construction permits the connection of a common, form of hoseknipple indicated at 23 to which a hose 24 is secured.

It is to be noted, that while my improvedcoupling is especially intended to permit convenient connection of garden hose with the ordinary faucets, it is by no means lim ited to this particular application and may 4be advantageously employed wherever a readily separable coupling is desired.

ln use, the female section 11 is connected vto the outlet of a faucet, as shown in Fig- .lugs are curved, the ends of the lugs being and close fitting joint. To prevent leaka e yof the liquid about the joints, itis desirab e to insert a suitable packing ring 25 in the groove 2 1 formed in the upper end of the male section, this packing ring being compressed by the downwardly project-ing sleeve` 18 to insure a tight connection. A similar packing ring or washer 26 may be positioned in the upper internally threaded bore 16 to secure a water pipe connection with the faucet. To uncouple the sections, it is merely necessary tov swing the lower male section 12 in a direction away from the exjoined claims.

Having thus described my invention, I claim:

1. A pipe coupling comprisingra female section having, a downwardly projecting extension, a collar formed in the said section, and a pair of parallel ribs formed at the lower edges of the downwardly projecting extension; a co-acting tubular male section, an annular flange formed about one end of the male section, a pair of ltapered lugs formed on the sides of the male section and integral with the annular flange and engageable with the ribs of the female section, the extremity of the male section being provided with an annular groove to receive the collar of the female section.

2. A pipe coupling comprising a pair of separable sections, one section including a body member having a threaded bore, the said member having a substantially semicircular extension, a collar formed within the body, and a pair of parallel ribsupon the lower portion of the extension; a male section including a tubular body having an annular flange formed at one end, tapered lugs form-ed on opposed sides of the male section and integral with the annular flange, the sai-d sections being adapted to be separably connected by angular movement of the male section with respect to lthefemale section whereby the lugs of the male section are slidably engaged with the ribs of the female section to connect the sections in alignment.

3. A pipe coupling comprising a pair of separable coupling sections, one section including a body member having a threaded bore engageable with a faucet, an arcuate downward extension formed on the body member, a collar formed in the body member having a downwardly depending sleeve extension, a pair of parallel tapered ribs formed on tlie inner sides of the arcuate ex-v tension, a complementary section embodying a tubular body, an annular flange formed at one end of the body, a pair of tapered lugs having arcuate sides formed on opposed sides of the body adjacent the flange, said annular flange being provided with an annular groove to receive the end of the sleeve formed on the complementary section, the

lsaid sections being adapted to be separably connected by angular movement of the last section whereby the tapered lugs engage the ribs formed on the opposite section for tight connection of these members.

4. A pipe coupling comprising a female coupling section including a body member for connection with a faucet, an arcuate extension forming a continuation of the body member, transversely extending ribs formed at the lower inner edges of the arcuate extension in opposed positions, a reducing collar formed in the body and provided with a sleeve projecting toward the transverse ribs; and a coacting male section including a tubular body, an annular flange formed at one end of the tubular body recessed to provide an annular groove to receive the4 end of the sleeve on the female section, a pair of tapered lugs formed in opposed relation on the sides of the tubular body adapted for slidable engagement with the transverse ribs f on the female section for adjustable connection of the sections. v

In-testimony'whereof I affix my signature.'
